Efficiently Finding Foreign Key Constraints Referencing a Table in SQL Server

Before deleting a heavily used table in SQL Server, it's vital to locate and drop all related foreign key constraints. A more efficient method than manually searching within the management studio is using the sp_fkeys stored procedure.

The sp_fkeys procedure accepts the table name as input and returns all foreign keys referencing that table. The query is executed as follows:

<code class="language-sql">EXEC sp_fkeys 'TableName'</code>

For tables within a specific schema, use this syntax:

<code class="language-sql">EXEC sp_fkeys @pktable_name = 'TableName', @pktable_owner = 'dbo'</code>

Omitting the schema uses SQL Server's default table visibility rules. As the documentation states, this prioritizes tables owned by the current user or the database owner.

Using sp_fkeys provides a complete list of foreign keys referencing a target table, ensuring database integrity when removing tables.
